Quantitative investment
Quantitative investment refers to a trading method in which orders for buying and selling are issued through quantitative methods and computer programming in order to obtain stable income. Its overseas development has a history of more than 30 years, its investment performance is stable, its market scale and share are expanding, and it has been recognized by more and more investors. Judging from the participants in the global market and the scale of assets under management, five of the top four or six asset management institutions in the world rely on computer technology to make investment decisions, and the scale of funds managed by quantitative and programmatic exchanges is expanding.
In fact, with the development of the Internet, this new concept has spread rapidly around the world. As a concept, quantitative investment is not new, and domestic investors have heard about it for a long time. However, real quantitative funds are rare in China. At the same time, the development of machine learning has also promoted quantitative investment.
The distinguishing feature of quantitative investment from qualitative investment is the model, and everyone is more concerned about the relationship between the model and people in quantitative investment. For example, to illustrate this relationship, let's look at the treatment of doctors. Traditional Chinese medicine and western medicine have different methods of diagnosis and treatment. The final judgment of Chinese medicine in seeing, smelling, asking and feeling is largely based on the experience of Chinese medicine and is qualitative. Western medicine is different. First of all, ask the patient to take a picture and have an examination. These all depend on medical instruments, and finally draw a conclusion and prescribe the right medicine.
There are some differences between qualitative investment and quantitative investment. These differences are just like the differences between Chinese medicine and western medicine. Qualitative investment is more like traditional Chinese medicine, relying more on experience and feeling to determine where the disease is. Quantitative investment is more like western medicine. From the point of view of the model, the model has the same effect on quantifying investment fund managers as the CT machine has on doctors. Before the investment operation every day, I will use the model to conduct a comprehensive investigation and scanning of the whole market, and then make investment decisions according to the results of the investigation and scanning.
